Is everyone else having trouble with a dysfunctionally slow LEED-Online today (i.e., worse than the usual incredibly slow performance)?

Were we given any warning that LEED Online and USGBC.org would be down for a week?  

Has anyone seen a comparison between IECC 2021 and previous versions of the energy code, including ASHRAE 2010? I'm curious how far ahead code buildings are relative to LEED v4.0, and how much the latest IECC raises the bar relative to the previous. I did a quick search for the LBNL and other studies that look at this, but didn't see anything... Read more
